Raber Ryan F 4

What Happened

• Ryan F. Raber, EVP — Strategy, Sales & Marketing at Mayville Engineering Company (MEC), exercised convertible derivative awards on March 15, 2026 and received shares, and concurrently had shares withheld to cover tax liability. The filing reports exercises/conversions of 17,650 and 12,452 shares (total 30,102 shares acquired via derivative exercise/conversion, reported at $0.00). To satisfy tax withholding or related payment, 14,150 shares were disposed at $16.67 per share for a total of $235,881.

• These transactions are primarily an exercise/conversion of derivatives with a share surrender to cover taxes (routine), not an open-market sale.

Context

• The 14,150-share disposition is a tax-withholding action commonly used after option exercises (a form of cashless withholding), not necessarily a market sell intended as investment timing.
• The awarded 29,155 RSUs are derivative grants subject to future vesting schedules (see footnotes); RSU grants and routine tax withholding are generally administrative and do not alone indicate insider sentiment.
